Russell King c48f16b42a net: phy: remove redundant .aneg_done initialisers
Remove initialisers that set .aneg_done to genphy_aneg_done - this is
the default for clause 22 PHYs, so the initialiser is redundant.

Kees Cook ca0e477931 ath11k: Use sizeof_field() instead of FIELD_SIZEOF()
The FIELD_SIZEOF() macro was redundant, and is being removed from the
kernel. Since commit c593642c8b ("treewide: Use sizeof_field() macro")
this is one of the last users of the old macro, so replace it.

Dedy Lansky 4315a74a48 wil6210: add support for set_cqm_rssi_config
set_cqm_rssi_config() is used by the kernel to configure connection
quality monitor RSSI threshold.
wil6210 uses WMI_SET_LINK_MONITOR_CMDID to set the RSSI threshold to
FW which in turn reports RSSI threshold changes with
WMI_LINK_MONITOR_EVENTID.

Ahmad Masri 5e5f069c30 wil6210: support set_multicast_to_unicast cfg80211 operation
Wil6210 AP has a separate ring for transmitting multicast packets,
multicast packets are transmitted without an ack from the receiver side.
Therefore, 802.11 spec defines some low MCS rates for multicat packets.
However, there is no guarantee that these packets were really received
and handled on the client side.

Some applications that rely on multicast packets, may prefer to
transmit these packets as a unicast to ensure reliability, and also
to ensure better performance with high MCS rates.
multicast to unicast is done by duplicating multicast packets to all
clients and changing the DA (multicast) to the MAC address of the
client.
see NL80211_CMD_SET_MULTICAST_TO_UNICAST for more info.

Maxim Mikityanskiy c0fdccfd22 net/ixgbe: Fix concurrency issues between config flow and XSK
Use synchronize_rcu to wait until the XSK wakeup function finishes
before destroying the resources it uses:

1. ixgbe_down already calls synchronize_rcu after setting __IXGBE_DOWN.

2. After switching the XDP program, call synchronize_rcu to let
ixgbe_xsk_wakeup exit before the XDP program is freed.

3. Changing the number of channels brings the interface down.

4. Disabling UMEM sets __IXGBE_TX_DISABLED before closing hardware
resources and resetting xsk_umem. Check that bit in ixgbe_xsk_wakeup to
avoid using the XDP ring when it's already destroyed. synchronize_rcu is
called from ixgbe_txrx_ring_disable.

Johan Hovold 960da557f4 rsi: add missing endpoint sanity checks
The driver expects at least one bulk-in endpoint when in "wifi-alone"
operating mode and two bulk-in endpoints otherwise, and would otherwise
fail to to submit the corresponding bulk URB to the default pipe during
probe with a somewhat cryptic message:

	rsi_91x: rsi_rx_urb_submit: Failed in urb submission
	rsi_91x: rsi_probe: Failed in probe...Exiting
	RSI-USB WLAN: probe of 2-2.4:1.0 failed with error -8

The current endpoint sanity check looks broken and would only bail out
early if there was no bulk-in endpoint but at least one bulk-out
endpoint.

Tighten this check to always require at least one bulk-in and one
bulk-out endpoint, and add the missing sanity check for a Bluetooth
bulk-in endpoint when in a BT operating mode. Also make sure to log an
informative error message when the expected endpoints are missing.

In the implementation of brcmf_p2p_create_p2pdev() the allocated memory
for p2p_vif is leaked when the mac address is the same as primary
interface. To fix this, go to error path to release p2p_vif via
brcmf_free_vif().

Eduardo Abinader f998f9fcf9 wcn36xx: disable HW_CONNECTION_MONITOR
Whenever the signal stregth decays smoothly and physical connnection
is already gone and no deauth has arrived, the qcom soc is not
able to indicate neither WCN36XX_HAL_MISSED_BEACON_IND nor
WCN36XX_HAL_MISSED_BEACON_IND. It was noticed that such situation gets
even more reproducible, when the driver fails to enter bmps mode - which is
highly likely to occur. Thus, in order to provide proper disconnection
of the connected STA, let mac80211 handle it, instead of wcn3xx driver.

Paul Durrant f55c3188df xen-netback: switch state to InitWait at the end of netback_probe()...
...as the comment above the function states.

The switch to Initialising at the start of the function is somewhat bogus
as the toolstack will have set that initial state anyway. To behave
correctly, a backend should switch to InitWait once it has set up all
xenstore values that may be required by a initialising frontend. This
patch calls backend_switch_state() to make the transition at the
appropriate point.

NOTE: backend_switch_state() ignores errors from xenbus_switch_state()
      and so this patch removes an error path from netback_probe(). This
      means a failure to change state at this stage (in the absence of
      other failures) will leave the device instantiated. This is highly
      unlikley to happen as a failure to change state would indicate a
      failure to write to xenstore, and that will trigger other error
      paths. Also, a 'stuck' device can still be cleaned up using 'unbind'
      in any case.

John Hurley 39f14c00b1 nfp: flower: fix stats id allocation
As flower rules are added, they are given a stats ID based on the number
of rules that can be supported in firmware. Only after the initial
allocation of all available IDs does the driver begin to reuse those that
have been released.

The initial allocation of IDs was modified to account for multiple memory
units on the offloaded device. However, this introduced a bug whereby the
counter that controls the IDs could be decremented before the ID was
assigned (where it is further decremented). This means that the stats ID
could be assigned as -1/0xfffffff which is out of range.

Fix this by only decrementing the main counter after the current ID has
been assigned.

Ben Hutchings cad46039e4 net: qlogic: Fix error paths in ql_alloc_large_buffers()
ql_alloc_large_buffers() has the usual RX buffer allocation
loop where it allocates skbs and maps them for DMA.  It also
treats failure as a fatal error.

There are (at least) three bugs in the error paths:

1. ql_free_large_buffers() assumes that the lrg_buf[] entry for the
first buffer that couldn't be allocated will have .skb == NULL.
But the qla_buf[] array is not zero-initialised.

2. ql_free_large_buffers() DMA-unmaps all skbs in lrg_buf[].  This is
incorrect for the last allocated skb, if DMA mapping failed.

3. Commit 1acb8f2a7a ("net: qlogic: Fix memory leak in
ql_alloc_large_buffers") added a direct call to dev_kfree_skb_any()
after the skb is recorded in lrg_buf[], so ql_free_large_buffers()
will double-free it.

The bugs are somewhat inter-twined, so fix them all at once:

* Clear each entry in qla_buf[] before attempting to allocate
  an skb for it.  This goes half-way to fixing bug 1.
* Set the .skb field only after the skb is DMA-mapped.  This
  fixes the rest.

- only allow the link modes that the specified PHY interface mode
  supports with the exception of 1000base-X and 2500base-X.
- use the basex helper to deal with SFP modules that can be switched
  between 1000base-X vs 2500base-X.

This gives consistent behaviour between mvneta and mvpp2.

This commit depends on "net: phylink: extend clause 45 PHY validation
workaround" so is not marked for backporting to stable kernels.

Russell King df3f57ac96 net: phylink: extend clause 45 PHY validation workaround
Commit e45d1f5288 ("net: phylink: support Clause 45 PHYs on SFP+
modules") added a workaround to support clause 45 PHYs which
dynamically switch their interface mode on SFP+ modules.  This was
implemented by validating the PHYs supported/advertising using
PHY_INTERFACE_MODE_NA, rather than the specific interface mode that
we attached the PHY with.

However, we already have a situation where phylink is used to connect
a Marvell 88X3310 PHY which also behaves in exactly the same way, but
which seemingly doesn't need this.  The reason seems to be that the
mvpp2 driver sets a whole bunch of link modes for
PHY_INTERFACE_MODE_10GKR down to 10Mb/s, despite 10GBASE-R not actually
supporting anything but 10Gb/s speeds.

When testing with drivers that (correctly) take the mvneta approach,
where the validate() method only returns what can be supported /
advertised for the specified link mode, we find that Clause 45 PHYs do
not behave as we expect: their advertisement is restricted to what
the current link will support, rather than what the PHY supports
through its dynamic switching.

Extend this workaround to all such cases; if we have a Clause 45 PHY
attaching via any means, except in USXGMII, XAUI and RXAUI which are
all unable to support this dynamic switching or have other solutions
to it, then we need to validate using PHY_INTERFACE_MODE_NA.

This should allow mvpp2 to switch to a more conformant validate()
implementation.

Russell King 5d57c32758 net: phylink: improve clause 45 PHY ksettings_set implementation
While testing ethtool with the Methode DM7052 module, it was noticed
that attempting to set the advertising mask results in the mask being
truncated to the support offered by the currently chosen PHY interface
mode.

When a PHY dynamically changes the PHY interface mode, limiting the
advertising mask in this way is not correct - if the PHY happened to
negotiate 10GBASE-T, and selected 10GBASE-R as the host interface, we
don't want to restrict the advertisement to just 10GBASE-* modes.

Rework setting the advertisement to take account of this; do not pass
the requested advertisement through phylink_validate(), but rely on
the advertisement restriction (supported mask) set when the PHY was
initially setup.

Taehee Yoo 94dc550a50 gtp: fix an use-after-free in ipv4_pdp_find()
ipv4_pdp_find() is called in TX packet path of GTP.
ipv4_pdp_find() internally uses gtp->tid_hash to lookup pdp context.
In the current code, gtp->tid_hash and gtp->addr_hash are freed by
->dellink(), which is gtp_dellink().
But gtp_dellink() would be called while packets are processing.
So, gtp_dellink() should not free gtp->tid_hash and gtp->addr_hash.
Instead, dev->priv_destructor() would be used because this callback
is called after all packet processing safely.

Test commands:
    ip link add veth1 type veth peer name veth2
    ip a a 172.0.0.1/24 dev veth1
    ip link set veth1 up
    ip a a 172.99.0.1/32 dev lo

    gtp-link add gtp1 &

    gtp-tunnel add gtp1 v1 200 100 172.99.0.2 172.0.0.2

Taehee Yoo 94a6d9fb88 gtp: fix wrong condition in gtp_genl_dump_pdp()
gtp_genl_dump_pdp() is ->dumpit() callback of GTP module and it is used
to dump pdp contexts. it would be re-executed because of dump packet size.

If dump packet size is too big, it saves current dump pointer
(gtp interface pointer, bucket, TID value) then it restarts dump from
last pointer.
Current GTP code allows adding zero TID pdp context but dump code
ignores zero TID value. So, last dump pointer will not be found.

In addition, this patch adds missing rcu_read_lock() in
gtp_genl_dump_pdp().

Taehee Yoo 6b01b1d9b2 gtp: do not allow adding duplicate tid and ms_addr pdp context
GTP RX packet path lookups pdp context with TID. If duplicate TID pdp
contexts are existing in the list, it couldn't select correct pdp context.
So, TID value  should be unique.
GTP TX packet path lookups pdp context with ms_addr. If duplicate ms_addr pdp
contexts are existing in the list, it couldn't select correct pdp context.
So, ms_addr value should be unique.

Mahesh Bandewar 5d485ed88d bonding: fix active-backup transition after link failure
After the recent fix in commit 1899bb3251 ("bonding: fix state
transition issue in link monitoring"), the active-backup mode with
miimon initially come-up fine but after a link-failure, both members
transition into backup state.

Following steps to reproduce the scenario (eth1 and eth2 are the
slaves of the bond):

    ip link set eth1 up
    ip link set eth2 down
    sleep 1
    ip link set eth2 up
    ip link set eth1 down
    cat /sys/class/net/eth1/bonding_slave/state
    cat /sys/class/net/eth2/bonding_slave/state

Andy Roulin 826f66b30c bonding: move 802.3ad port state flags to uapi
The bond slave actor/partner operating state is exported as
bitfield to userspace, which lacks a way to interpret it, e.g.,
iproute2 only prints the state as a number:

ad_actor_oper_port_state 15

For userspace to interpret the bitfield, the bitfield definitions
should be part of the uapi. The bitfield itself is defined in the
802.3ad standard.

This commit moves the 802.3ad bitfield definitions to uapi.

Related iproute2 patches, soon to be posted upstream, use the new uapi
headers to pretty-print bond slave state, e.g., with ip -d link show

ad_actor_oper_port_state_str <active,short_timeout,aggregating,in_sync>

Driver doesn't calculate total number of PFs configured on a
given engine correctly which messed up resources in the PFs
loaded on that engine, leading driver to exceed configuration
of resources (like vlan filters etc.) beyond the limit per
engine, which ended up with asserts from the firmware.

Parity error from the hardware will cause PF to lose the state
of their VFs due to PF's internal reload and hardware reset following
the parity error. Restrict any configuration request from the VFs after
the parity as it could cause unexpected hardware behavior, only way
for VFs to recover would be to trigger FLR on VFs and reload them.

Russell King f3f2364ea1 net: marvell: mvpp2: phylink requires the link interrupt
phylink requires the MAC to report when its link status changes when
operating in inband modes.  Failure to report link status changes
means that phylink has no idea when the link events happen, which
results in either the network interface's carrier remaining up or
remaining permanently down.

For example, with a fiber module, if the interface is brought up and
link is initially established, taking the link down at the far end
will cut the optical power.  The SFP module's LOS asserts, we
deactivate the link, and the network interface reports no carrier.

When the far end is brought back up, the SFP module's LOS deasserts,
but the MAC may be slower to establish link.  If this happens (which
in my tests is a certainty) then phylink never hears that the MAC
has established link with the far end, and the network interface is
stuck reporting no carrier.  This means the interface is
non-functional.

Avoiding the link interrupt when we have phylink is basically not
an option, so remove the !port->phylink from the test.

Jakub Kicinski 1d1997db87 Revert "nfp: abm: fix memory leak in nfp_abm_u32_knode_replace"
This reverts commit 78beef629f ("nfp: abm: fix memory leak in
nfp_abm_u32_knode_replace").

The quoted commit does not fix anything and resulted in a bogus
CVE-2019-19076.

If match is NULL then it is known there is no matching entry in
list, hence, calling nfp_abm_u32_knode_delete() is pointless.

Jonathan Lemon 6adc4601c2 bnxt: apply computed clamp value for coalece parameter
After executing "ethtool -C eth0 rx-usecs-irq 0", the box becomes
unresponsive, likely due to interrupt livelock.  It appears that
a minimum clamp value for the irq timer is computed, but is never
applied.

Fix by applying the corrected clamp value.

Toke Høiland-Jørgensen 911bde0fe5 mac80211: Turn AQL into an NL80211_EXT_FEATURE
Instead of just having an airtime flag in debugfs, turn AQL into a proper
NL80211_EXT_FEATURE, so drivers can turn it on when they are ready, and so
we also expose the presence of the feature to userspace.

This also has the effect of flipping the default, so drivers have to opt in
to using AQL instead of getting it by default with TXQs. To keep
functionality the same as pre-patch, we set this feature for ath10k (which
is where it is needed the most).

While we're at it, split out the debugfs interface so AQL gets its own
per-station debugfs file instead of using the 'airtime' file.

[Johannes:]
This effectively disables AQL for iwlwifi, where it fixes a number of
issues:
 * TSO in iwlwifi is causing underflows and associated warnings in AQL
 * HE (802.11ax) rates aren't reported properly so at HE rates, AQL could
   never have a valid estimate (it'd use 6 Mbps instead of up to 2400!)

Michael S. Tsirkin 0290bd291c netdev: pass the stuck queue to the timeout handler
This allows incrementing the correct timeout statistic without any mess.
Down the road, devices can learn to reset just the specific queue.

Russell King 52c956003a net: phylink: delay MAC configuration for copper SFP modules
Knowing whether we need to delay the MAC configuration because a module
may have a PHY is useful to phylink to allow NBASE-T modules to work on
systems supporting no more than 2.5G speeds.

This commit allows us to delay such configuration until after the PHY
has been probed by recording the parsed capabilities, and if the module
may have a PHY, doing no more until the module_start() notification is
called.  At that point, we either have a PHY, or we don't.

We move the PHY-based setup a little later, and use the PHYs support
capabilities rather than the EEPROM parsed capabilities to determine
whether we can support the PHY.

Russell King 74c551ca5a net: sfp: add module start/stop upstream notifications
When dealing with some copper modules, we can't positively know the
module capabilities are until we have probed the PHY. Without the full
capabilities, we may end up failing a module that we could otherwise
drive with a restricted set of capabilities.

An example of this would be a module with a NBASE-T PHY plugged into
a host that supports phy interface modes 2500BASE-X and SGMII. The
PHY supports 10GBASE-R, 5000BASE-X, 2500BASE-X, SGMII interface modes,
which means a subset of the capabilities are compatible with the host.

However, reading the module EEPROM leads us to believe that the module
only supports ethtool link mode 10GBASE-T, which is incompatible with
the host - and thus results in the module being rejected.

This patch adds an extra notification which are triggered after the
SFP module's PHY probe, and a corresponding notification just before
the PHY is removed.

In netpoll the napi handler could be called with budget equal to zero.
Current ENA napi handler doesn't take that into consideration.

The napi handler handles Rx packets in a do-while loop.
Currently, the budget check happens only after decrementing the
budget, therefore the napi handler, in rare cases, could run over
MAX_INT packets.

In addition to that, this moves all budget related variables to int
calculation and stop mixing u32 to avoid ambiguity

Vasundhara Volam 937f188c1f bnxt_en: Fix the logic that creates the health reporters.
Fix the logic to properly check the fw capabilities and create the
devlink health reporters only when needed.  The current code creates
the reporters unconditionally as long as bp->fw_health is valid, and
that's not correct.

Call bnxt_dl_fw_reporters_create() directly from the init and reset
code path instead of from bnxt_dl_register().  This allows the
reporters to be adjusted when capabilities change.  The same
applies to bnxt_dl_fw_reporters_destroy().

Vasundhara Volam 0797c10d2d bnxt_en: Remove unnecessary NULL checks for fw_health
After fixing the allocation of bp->fw_health in the previous patch,
the driver will not go through the fw reset and recovery code paths
if bp->fw_health allocation fails.  So we can now remove the

Vasundhara Volam 8280b38e01 bnxt_en: Fix bp->fw_health allocation and free logic.
bp->fw_health needs to be allocated for either the firmware initiated
reset feature or the driver initiated error recovery feature.  The
current code is not allocating bp->fw_health for all the necessary cases.
This patch corrects the logic to allocate bp->fw_health correctly when
needed.  If allocation fails, we clear the feature flags.

We also add the the missing kfree(bp->fw_health) when the driver is
unloaded.  If we get an async reset message from the firmware, we also
need to make sure that we have a valid bp->fw_health before proceeding.

Luca Coelho 0df36b90c4 iwlwifi: pcie: move power gating workaround earlier in the flow
We need to reset the NIC after setting the bits to enable power
gating and that cannot be done too late in the flow otherwise it
cleans other registers and things that were already configured,
causing initialization to fail.

In order to fix this, move the function to the common code in trans.c
so it can be called directly from there at an earlier point, just
after the reset we already do during initialization.

Eric Dumazet 9e99bfefdb bonding: fix bond_neigh_init()
1) syzbot reported an uninit-value in bond_neigh_setup() [1]

 bond_neigh_setup() uses a temporary on-stack 'struct neigh_parms parms',
 but only clears parms.neigh_setup field.

 A stacked bonding device would then enter bond_neigh_setup()
 and read garbage from parms->dev.

 If we get really unlucky and garbage is matching @dev, then we
 could recurse and eventually crash.

 Let's make sure the whole structure is cleared to avoid surprises.

2) bond_neigh_setup() can be called while another cpu manipulates
 the master device, removing or adding a slave.
 We need at least rcu protection to prevent use-after-free.

Note: Prior code does not support a stack of bonding devices,
      this patch does not attempt to fix this, and leave a comment instead.

Jason A. Donenfeld e7096c131e net: WireGuard secure network tunnel
WireGuard is a layer 3 secure networking tunnel made specifically for
the kernel, that aims to be much simpler and easier to audit than IPsec.
Extensive documentation and description of the protocol and
considerations, along with formal proofs of the cryptography, are
available at:

  * https://www.wireguard.com/
  * https://www.wireguard.com/papers/wireguard.pdf

This commit implements WireGuard as a simple network device driver,
accessible in the usual RTNL way used by virtual network drivers. It
makes use of the udp_tunnel APIs, GRO, GSO, NAPI, and the usual set of
networking subsystem APIs. It has a somewhat novel multicore queueing
system designed for maximum throughput and minimal latency of encryption
operations, but it is implemented modestly using workqueues and NAPI.
Configuration is done via generic Netlink, and following a review from
the Netlink maintainer a year ago, several high profile userspace tools
have already implemented the API.

This commit also comes with several different tests, both in-kernel
tests and out-of-kernel tests based on network namespaces, taking profit
of the fact that sockets used by WireGuard intentionally stay in the
namespace the WireGuard interface was originally created, exactly like
the semantics of userspace tun devices. See wireguard.com/netns/ for
pictures and examples.

The source code is fairly short, but rather than combining everything
into a single file, WireGuard is developed as cleanly separable files,
making auditing and comprehension easier. Things are laid out as
follows:

  * noise.[ch], cookie.[ch], messages.h: These implement the bulk of the
    cryptographic aspects of the protocol, and are mostly data-only in
    nature, taking in buffers of bytes and spitting out buffers of
    bytes. They also handle reference counting for their various shared
    pieces of data, like keys and key lists.

  * ratelimiter.[ch]: Used as an integral part of cookie.[ch] for
    ratelimiting certain types of cryptographic operations in accordance
    with particular WireGuard semantics.

  * allowedips.[ch], peerlookup.[ch]: The main lookup structures of
    WireGuard, the former being trie-like with particular semantics, an
    integral part of the design of the protocol, and the latter just
    being nice helper functions around the various hashtables we use.

  * device.[ch]: Implementation of functions for the netdevice and for
    rtnl, responsible for maintaining the life of a given interface and
    wiring it up to the rest of WireGuard.

  * peer.[ch]: Each interface has a list of peers, with helper functions
    available here for creation, destruction, and reference counting.

  * socket.[ch]: Implementation of functions related to udp_socket and
    the general set of kernel socket APIs, for sending and receiving
    ciphertext UDP packets, and taking care of WireGuard-specific sticky
    socket routing semantics for the automatic roaming.

  * netlink.[ch]: Userspace API entry point for configuring WireGuard
    peers and devices. The API has been implemented by several userspace
    tools and network management utility, and the WireGuard project
    distributes the basic wg(8) tool.

  * queueing.[ch]: Shared function on the rx and tx path for handling
    the various queues used in the multicore algorithms.

  * send.c: Handles encrypting outgoing packets in parallel on
    multiple cores, before sending them in order on a single core, via
    workqueues and ring buffers. Also handles sending handshake and cookie
    messages as part of the protocol, in parallel.

  * receive.c: Handles decrypting incoming packets in parallel on
    multiple cores, before passing them off in order to be ingested via
    the rest of the networking subsystem with GRO via the typical NAPI
    poll function. Also handles receiving handshake and cookie messages
    as part of the protocol, in parallel.

  * timers.[ch]: Uses the timer wheel to implement protocol particular
    event timeouts, and gives a set of very simple event-driven entry
    point functions for callers.

  * main.c, version.h: Initialization and deinitialization of the module.

  * selftest/*.h: Runtime unit tests for some of the most security
    sensitive functions.

  * tools/testing/selftests/wireguard/netns.sh: Aforementioned testing
    script using network namespaces.

This commit aims to be as self-contained as possible, implementing
WireGuard as a standalone module not needing much special handling or
coordination from the network subsystem. I expect for future
optimizations to the network stack to positively improve WireGuard, and
vice-versa, but for the time being, this exists as intentionally
standalone.

We introduce a menu option for CONFIG_WIREGUARD, as well as providing a
verbose debug log and self-tests via CONFIG_WIREGUARD_DEBUG.

Joakim Zhang 048e3a34a2 can: flexcan: poll MCR_LPM_ACK instead of GPR ACK for stop mode acknowledgment
Stop Mode is entered when Stop Mode is requested at chip level and
MCR[LPM_ACK] is asserted by the FlexCAN.

Double check with IP owner, the MCR[LPM_ACK] bit should be polled for
stop mode acknowledgment, not the acknowledgment from chip level which
is used to gate flexcan clocks.

The MCR[LPMACK] read-only bit indicates that FlexCAN is in a lower-power
mode (Disabled mode, Doze mode, Stop mode).

The CPU can poll this bit to know when FlexCAN has actually entered low
power mode. The low power enter/exit acknowledgment helper will reduce
code duplication for disabled mode, doze mode and stop mode.

Sean Nyekjaer e707180ae2 can: flexcan: fix possible deadlock and out-of-order reception after wakeup
When suspending, and there is still CAN traffic on the interfaces the
flexcan immediately wakes the platform again. As it should :-). But it
throws this error msg:

[ 3169.378661] PM: noirq suspend of devices failed

On the way down to suspend the interface that throws the error message
calls flexcan_suspend() but fails to call flexcan_noirq_suspend(). That
means flexcan_enter_stop_mode() is called, but on the way out of suspend
the driver only calls flexcan_resume() and skips flexcan_noirq_resume(),
thus it doesn't call flexcan_exit_stop_mode(). This leaves the flexcan
in stop mode, and with the current driver it can't recover from this
even with a soft reboot, it requires a hard reboot.

This patch fixes the deadlock when using self wakeup, by calling
flexcan_exit_stop_mode() from flexcan_resume() instead of
flexcan_noirq_resume().

This also fixes another issue: CAN frames are received out-of-order in
first IRQ handler run after wakeup.

The problem is that the wakeup latency from frame reception to the IRQ
handler (where the CAN frames are sorted by timestamp) is much bigger
than the time stamp counter wrap around time. This means it's
impossible to sort the CAN frames by timestamp.

The reason is that the controller exits stop mode during noirq resume,
which means it receives frames immediately, but interrupt handling is
still not possible.

So exit stop mode during resume stage instead of noirq resume fixes this
issue.

Grygorii Strashko fafc5db28a net: phy: dp83867: fix hfs boot in rgmii mode
The commit ef87f7da6b ("net: phy: dp83867: move dt parsing to probe")
causes regression on TI dra71x-evm and dra72x-evm, where DP83867 PHY is
used in "rgmii-id" mode - the networking stops working.
Unfortunately, it's not enough to just move DT parsing code to .probe() as
it depends on phydev->interface value, which is set to correct value abter
the .probe() is completed and before calling .config_init(). So, RGMII
configuration can't be loaded from DT.

To fix and issue
- move RGMII validation code to .config_init()
- parse RGMII parameters in dp83867_of_init(), but consider them as
optional.

Bruno Carneiro da Cunha 04aa1bc42e lpc_eth: kernel BUG on remove
We may have found a bug in the nxp/lpc_eth.c driver. The function
platform_set_drvdata() is called twice, the second time it is called,
in lpc_mii_init(), it overwrites the struct net_device which should be
at pdev->dev->driver_data with pldat->mii_bus. When trying to remove
the driver, in lpc_eth_drv_remove(), platform_get_drvdata() will
return the pldat->mii_bus pointer and try to use it as a struct
net_device pointer. This causes unregister_netdev to segfault and
generate a kernel BUG. Is this reproducible?

Jongsung Kim f421031e3f net: stmmac: reset Tx desc base address before restarting Tx
Refer to the databook of DesignWare Cores Ethernet MAC Universal:

6.2.1.5 Register 4 (Transmit Descriptor List Address Register

If this register is not changed when the ST bit is set to 0, then
the DMA takes the descriptor address where it was stopped earlier.

The stmmac_tx_err() does zero indices to Tx descriptors, but does
not reset HW current Tx descriptor address. To fix inconsistency,
the base address of the Tx descriptors should be rewritten before
restarting Tx.

Yangbo Lu a6a10d45d1 enetc: disable EEE autoneg by default
The EEE support has not been enabled on ENETC, but it may connect
to a PHY which supports EEE and advertises EEE by default, while
its link partner also advertises EEE. If this happens, the PHY enters
low power mode when the traffic rate is low and causes packet loss.
This patch disables EEE advertisement by default for any PHY that
ENETC connects to, to prevent the above unwanted outcome.

Yunsheng Lin d1a37dedcf net: hns3: fix a use after free problem in hns3_nic_maybe_stop_tx()
Currently, hns3_nic_maybe_stop_tx() uses skb_copy() to linearize a
SKB if the BD num required by the SKB does not meet the hardware
limitation, and it linearizes the SKB by allocating a new linearized SKB
and freeing the old SKB, if hns3_nic_maybe_stop_tx() returns -EBUSY
because there are no enough space in the ring to send the linearized
skb to hardware, the sch_direct_xmit() still hold reference to old SKB
and try to retransmit the old SKB when dev_hard_start_xmit() return
TX_BUSY, which may cause use after freed problem.

This patch fixes it by using __skb_linearize() to linearize the
SKB in hns3_nic_maybe_stop_tx().

There is timing window between ring_space checking and
netif_stop_subqueue when transmiting a SKB, and the TX BD
cleaning may be executed during the time window, which may
caused TX queue not restarted problem.

This patch fixes it by rechecking the ring_space after
netif_stop_subqueue to make sure TX queue is restarted.

Also, the ring->next_to_clean is updated even when pkts is
zero, because all the TX BD cleaned may be non-SKB, so it
needs to check if TX queue need to be restarted.

In cited commit, when prio tag mode is enabled, FTE creation fails
due to missing group with valid match criteria.

Hence,
(a) create prio tag group metadata_prio_tag_grp when prio tag is

(b) Rename metadata_grp to metadata_allmatch_grp to reflect its purpose.

Also when priority tag is enabled, delete metadata settings after

Eran Ben Elisha c55d8b108c net/mlx5e: Fix TXQ indices to be sequential
Cited patch changed (channel index, tc) => (TXQ index) mapping to be a
static one, in order to keep indices consistent when changing number of
channels or TCs.

For 32 channels (OOB) and 8 TCs, real num of TXQs is 256.
When reducing the amount of channels to 8, the real num of TXQs will be
changed to 64.
This indices method is buggy:
- Channel #0, TC 3, the TXQ index is 96.
- Index 8 is not valid, as there is no such TXQ from driver perspective
  (As it represents channel #8, TC 0, which is not valid with the above
  configuration).

As part of driver's select queue, it calls netdev_pick_tx which returns an
index in the range of real number of TXQs. Depends on the return value,
with the examples above, driver could have returned index larger than the
real number of tx queues, or crash the kernel as it tries to read invalid
address of SQ which was not allocated.

Fix that by allocating sequential TXQ indices, and hold a new mapping
between (channel index, tc) => (real TXQ index). This mapping will be
updated as part of priv channels activation, and is used in
mlx5e_select_queue to find the selected queue index.

The existing indices mapping (channel_tc2txq) is no longer needed, as it
is used only for statistics structures and can be calculated on run time.
Delete its definintion and updates.

ipv6_stub uses the ip6_dst_lookup function to allow other modules to
perform IPv6 lookups. However, this function skips the XFRM layer
entirely.

All users of ipv6_stub->ip6_dst_lookup use ip_route_output_flow (via the
ip_route_output_key and ip_route_output helpers) for their IPv4 lookups,
which calls xfrm_lookup_route(). This patch fixes this inconsistent
behavior by switching the stub to ip6_dst_lookup_flow, which also calls
xfrm_lookup_route().

This requires some changes in all the callers, as these two functions
take different arguments and have different return types.

Vladimir Oltean 9385973fe8 net: mscc: ocelot: unregister the PTP clock on deinit
Currently a switch driver deinit frees the regmaps, but the PTP clock is
still out there, available to user space via /dev/ptpN. Any PTP
operation is a ticking time bomb, since it will attempt to use the freed
regmaps and thus trigger kernel panics:

Slcan_open doesn't clean-up device which registration failed from the

device is accessed. Fix this by calling slc_free_netdev in error path.

Driver/net/can/slcan.c is derived from slip.c. Use-after-free error was

Linus Torvalds 937d6eefc7 Here's the main documentation changes for 5.5:
- Various kerneldoc script enhancements.
 
  - More RST conversions; those are slowing down as we run out of things to
    convert, but we're a ways from done still.
 
  - Dan's "maintainer profile entry" work landed at last.  Now we just need
    to get maintainers to fill in the profiles...
 
  - A reworking of the parallel build setup to work better with a variety of
    systems (and to not take over huge systems entirely in particular).
 
  - The MAINTAINERS file is now converted to RST during the build.
    Hopefully nobody ever tries to print this thing, or they will need to
    load a lot of paper.
 
  - A script and documentation making it easy for maintainers to add Link:
    tags at commit time.
 
 Also included is the removal of a bunch of spurious CR characters.

qize wang 1e58252e33 mwifiex: Fix heap overflow in mmwifiex_process_tdls_action_frame()
mwifiex_process_tdls_action_frame() without checking
the incoming tdls infomation element's vality before use it,
this may cause multi heap buffer overflows.

Fix them by putting vality check before use it.

IE is TLV struct, but ht_cap and  ht_oper aren’t TLV struct.
the origin marvell driver code is wrong:

memcpy(&sta_ptr->tdls_cap.ht_oper, pos,....
memcpy((u8 *)&sta_ptr->tdls_cap.ht_capb, pos,...

Fix the bug by changing pos(the address of IE) to
pos+2 ( the address of IE value ).

Wen Gong 2dc016599c ath: add support for special 0x0 regulatory domain
Some sdio chips of rome QCA6174's regulatory domain code of EEPROM is
empty, then ath_is_world_regd will return false for this case, and
it will lead function __ath_reg_dyn_country not work, thus the regdomain
will not update for NL80211_REGDOM_SET_BY_COUNTRY_IE type, it result
ath10k set the same regdomain/reg_5ghz_ctl/reg_2ghz_ctl to firmware,
then the tx power will not changed with different regdomain's AP. The
regulatory domain code of EEPROM of some QCA6174 PCIE chip is 0x6c, it
means world wide regdomain, for this chip, it does not have the issue.

For empty reulatory domain code chip, set it to world regulatory domain
in functio ath_regd_sanitize, then it will fix the issue.

Wen Gong 4a99124516 ath10k: change bundle count for max rx bundle for sdio
For max bundle size 32, the bundle mask is not same with 8/16.
Change it to match the max bundle size of htc. Otherwise it
will not match with firmware, for example, when bundle count
is 17, then flags of ath10k_htc_hdr is 0x4, if without this
patch, it will be considered as non-bundled packet because it
does not have mask 0xF0, then trigger error message later:
payload length 56747 exceeds max htc length: 4088.

htc->max_msgs_per_htc_bundle is the min value of
HTC_HOST_MAX_MSG_PER_RX_BUNDLE and
msg->ready_ext.max_msgs_per_htc_bundle of ath10k_htc_wait_target,
it will be sent to firmware later in ath10k_htc_start, then
firmware will use it as the final max rx bundle count, in
WLAN.RMH.4.4.1-00029, msg->ready_ext.max_msgs_per_htc_bundle
is 32, it is same with HTC_HOST_MAX_MSG_PER_RX_BUNDLE, so the
final max rx bundle count will be set to 32 in firmware.

This patch only effect sdio chips.

Wen Gong cfee8793a7 ath10k: enable napi on RX path for sdio
For tcp RX, the quantity of tcp acks to remote is 1/2 of the quantity
of tcp data from remote, then it will have many small length packets
on TX path of sdio bus, then it reduce the RX packets's bandwidth of
tcp.

This patch enable napi on RX path, then the RX packet of tcp will not
feed to tcp stack immeditely from mac80211 since GRO is enabled by
default, it will feed to tcp stack after napi complete, if rx bundle
is enabled, then it will feed to tcp stack one time for each bundle
of RX. For example, RX bundle size is 32, then tcp stack will receive
one large length packet, its length is neary 1500*32, then tcp stack
will send a tcp ack for this large packet, this will reduce the tcp
acks ratio from 1/2 to 1/32. This results in significant performance
improvement for tcp RX.

Tcp rx throughout is 240Mbps without this patch, and it arrive 390Mbps
with this patch. The cpu usage has no obvious difference with and
without NAPI.

Linus Torvalds 0da522107e compat_ioctl: remove most of fs/compat_ioctl.c
As part of the cleanup of some remaining y2038 issues, I came to
 fs/compat_ioctl.c, which still has a couple of commands that need support
 for time64_t.
 
 In completely unrelated work, I spent time on cleaning up parts of this
 file in the past, moving things out into drivers instead.
 
 After Al Viro reviewed an earlier version of this series and did a lot
 more of that cleanup, I decided to try to completely eliminate the rest
 of it and move it all into drivers.
 
 This series incorporates some of Al's work and many patches of my own,
 but in the end stops short of actually removing the last part, which is
 the scsi ioctl handlers. I have patches for those as well, but they need
 more testing or possibly a rewrite.

Also refactoring ath11k_mac_create() into ath11k_mac_alloc() and

wmi_init command.

Manikanta Pubbisetty 28dee8ef76 ath11k: fix vht guard interval mapping
Guard interval value which comes from VHT_SIG_A TLV has a mapping
where value 0 corresponds to LGI, 1 and 3 corresponds to SGI.

Value 3 which is SGI(0.4us) in VHT was incorrectly mapped to a GI
of 3.2us(only applicable in HE) resulting in incorrect rx GI stats.
Fixing the mapping.

Maharaja Kennadyrajan 64f1d7e94d ath11k: add support for controlling tx power to a station
This patch will add the support to control the transmit power
for traffic to a station associated with the AP.

Underlying firmware will enforce that the maximum tx power will
be based on the regulatory requirements. If the user given
transmit power is greater than the allowed tx power in the given
channel, then the firmware will use the maximum tx power in the
same channel.

Max and Min tx power values will depends on number of tx chain
masks. The allowed tx power range values are from 6 to 23.

When 0 is sent to the firmware as tx power, it will revert to
the default tx power for the station.

Currenly in delba process calling ath11k_peer_rx_tid_delete() updates
reo with desc invalid and add tid queue to the flush list. If station
send data traffic without addba req and before tid flush, hw gives
those packets as invalid desc reo error. Since we are dropping these
invalid desc packets results in traffic stall.

This patch fix this issue by updating the reo queue with bawindow size 1
instead of tid removal in delba process.
